to theree'dle of asewinginacliine for stitch-v ing. Subsequenty totherst operation of the stitching machineh the. book is'` movedautomatiszaily to make thestitches therein equally spaced apart,throughout 'the height of" the book.z After thedirst stitch made,the.osif tionsoftherstitches tio-follow are fixed.; ence albook must bepresented to the needle; in such away that the first stitchv will' be ata proper distancerfrom the edge ofthe book,j that any stitches followingwill not register with the metal staple@ and the last stitch wilT occurat' the desired.l distancefrom the opposite edge othe book. l i

The( above. described task requires the ehtire; time and concentratedattention of' an operator to effect stitches which, at the,` best, only'approximate the desired position.

AsV book 121iis pushed backward yby the'l pusher. bars 7 2 and 73, itisnecessary that the book be delivered exactly toa predetermined position,and at the end of .the backward stroke'of said bars. Concurrently, footl126 y of the stitching machine is lowered to insurel theili'xedplacement of book 121 until a' seclond foot 127 and pawl plate 150bothof thestitching machine (see Figures2 and 6) move Y forward tocoengage the'book 121 to advancel Vformly spaced, and thelinished bookitself isfmeasurably laid out; Once the'book 120 visenga'ged byfoot 126,it is subsequently ad-k Y vancedbythe pawl plate 150 and. foot 127,

VPoint 151, 'where the'first insertion of the needleis made, is sochosen that the margin fromsaid point to the lower edge ofthe iinishedbook as laid out will be equal to the marginfrom the last'insertion orstitch near the top of the book to the top edgeof said finished book.The steel staples previously placed in the bookare so spaced that theywill not "coincide with-stitches laid out'sas above de-v scribed. f

kvThe device is set for a run of booksof a given size inV the'followingmanner. It willl be noted that needle 124 completes a stitching-cyclefor each revolution ofthe'sprocket 152 of the stitching machine. Thefeedingl vdevice performs a complete cycle for each irevolutionof gearwheel 32. The needle 124. makes one cycle: between each preceding andsucceeding book to ypenetrate neither book. It is then conceivable thatwhenv theV number of stitches to be placed in each: book of a givenuniform run has been determined, a gear wheel32 must be selected of adiameter to complete onerevolution concurrent to that number ofystitches plus one., For example,

if each book'of a run was to receive eight stitches, the turning ratioof gear 32 to l .sprocket 152'must be nine to one. l

The racks 67 vand 68l and pusher barsv 72 and are` next adjusted for theheight of.` the books. rThe kbook feeding device is operated until saidracks are in the extreme l tothe back face of plate? to not obstruct abook 120 to "drop down into place. -The de- 'vice is operated vagain andthrough` a half `books of a greater width, set screws 81 are Va positionthat the first stitch will be propcycle untilthe pusher bars are in therear-V most position and book 120 has been transported to position 121'.4 '.1 fr Y VvAt this time it may be found that point 151 on book 121 isnot at the desired Vpoint of advancement, and, if not, nut associatedwith gear wheel. 58 is loosened to thereby, free shaft 61 from gear 58and the preceding link# age. Afwrenchis'now applied to the con-V formingend 61a of shaft 61 toro'tate said shaft, and'gears 65and 66, untilpusher bars 7 2 vand 73 are positioned to deliver book 121 so' thatpoint 151 is at the properk advanced position. neet shaft 61 again inthe linkage of the device. v v f 3 v o Vhen books of a greaterheightIare to be handled by the device, nut 84 is loosened so` that plate maybe moved forward to suitably enlarge the hopper.

Blindchannels 128 are pro,-

vided in the top 114 of the stitching machine to'receive ythe ends ofracks 67 `and68, and, in case the pusher bars are ever set forward onthe racks, to necessitate a further'back- 1 wardfmovement of said racksVto deliver .a book 121 to the desired position. A. v, p

Pusherbars 72 and 73 are ofE suiiicient length that when in the backpositionto deliver la book, the vfron-t portion thereof will A remainvunder books 120- and to prevent the .lowerl one from dropping down toobstruct the return forward movement of the bars. These pusher bars areprovided in different heights orwith shims whereby adjustment .110

the lower Vbook onlywhen discharging it 'fromV 1,15 the hopper.

\ Besides insuring the book 120 to becontiguous to guiding flange 122,leaf springs v115 `serve a dual purpose of retarding further progress ofsaid book lafterit has lbeen delivered to the desired position by the`pusher v bars. It isthe function ofvthis bookvfeeding'device to delivera `book tol needle 124 in such erly located as to place thek subsequentstitches where desired. 'Alecto deliver books 120 at such yintervalsthat only one operation of the "needle will intervenewhileno bookisvunder said needle. Whilegthebook 120 is kbeing 130.

Nut, 60 is then tightened tocon- Y and 73 are being moved forward. When,at

-the end of this forward movement, the

back ends of said pusher bars are beyond the back side of plate 75, asecond book `120 immediately drops down to the rear of the pusher barsto be engaged and pushed rearward on the following stroke. Thus thecycle is again started whereby a second book 120 will be delivered toand engaged by feet 126 and 127 to be carried under the needle. 'f

A second embodiment of the invention which comprises a feeding devicewhich delivers a book to the vfeet ofthe machine in a similar manner tothe above described machine, but which is fed by hand rather thanautomatically from a hopper,will now be described.

In Figure 6 a bar 130 is shown attached by set screws 131 to areciprocating member 132 contained withinthe stitching machine. The

forward end of bar 130 protrudes through an opening 133 provided in thefront wall of the stitching machine, and there is bifurcated and drilledto contain a pin 134. Pin 134 engages a link 135, the other end of saidlink 135 terminating in a joint 136 and in the lower portion of a gib137.

Secured to the front wall138 of the stitching machine by means ofmachine screws 139, is a plate in the form of a bracket 140, the top ofwhich is Hush with the top of the stitching machine. The plate 140extends to the front and contains therein a longitudinal slot 141, inthe latter of which is contained gib 137. Lying flatly upon the upperface of bracket 140 is a member comprising a pusherv bar 142 with abroadened and flat face 143. Pusher plate or bar 142 has within it aslot 144 parallel and in juxtaposition to slotl 141. Transversingnormally slots 141 and 144 to engage gib 137 is a bolt 145.

When bar 130, hence pusher plate 142, is in its most forward position, abook 146 is placed and with its squared top adjacent face 143 and withits back against guiding iange 1.22 of plate 123 (see Figures land 6).On the backward motion of crank 148, bar 130, and face 143; the bottomedge of said book is brought to the position as shown in Figure 6 wherepoint 151 is as desired, and to be left in that position by the pusherplate 142 as it returns on the subsequent forward stroke.

The book 146 is operated upon when delivered to this forward position inthe same manner as described in the previous embodiment of theinvention. As the face 143 again position, if .i book 146er a, greatheight is being prodded thereby, the face 143 must be necessarilyfurther forward, that the bottom of the book will not extend beyond theneedle. V

Also, with a book of lesser height on the eX- treme rear position of thestroke, face 143 must be nearer the needle.

What is claimed to be new and it is desired to .be secured by LettersPatent in these United States, is:

1. A book feeding device adapted to be connected to and operateconjointly with a book stitching machine having means for advancing agroup of signatures 'by a predetermined intermittent mo-tion, and,`coinprising a pusher bar, means for moving Asaid pusher bar at thejsamespeed ais-said advancing means, fand means for retracting said pusherbar to permit of onestitch being taken intermediate succeeding booksadvanced to said stitching machine.

2.
